SIP/VoIP Services.

SIP trunking is the perfect solution for companies looking to take advantage of a fully integrated, flexible and future-proof telecommunications solution.

No longer considered a future technology, over 1.5 million business users are now fully leveraging the flexibility and mobility offered by SIP and VoIP solutions to support their evolving work environment.

At Arden Group our experienced team of dedicated account managers and engineers have the knowledge and expertise to quickly integrate and deliver a secure SIP network that delivers results.


  • It’s scalable.

    The simplicity of installing additional services and users makes VoIP an ideal candidate for companies looking for the flexibility to scale up or scale down their telephone network. Perfect for those looking for an adaptive solution that actively supports their individual growth initiatives.

  • Simple integration.

    Setting up and installing a VoIP solution is incredibly easy, especially with the support of a dedicated communications provider. Evaluating the required bandwidth and network capacity, your provider will recommend and install the best equipment to support your individual business requirements.

  • Quality’s not an issue.

    Back when internet connections were unreliable VoIP struggled to compare with ISDN in terms of quality. Now, with superfast broadband and QoS, businesses can enjoy crisp, clear VoIP along with the added security of auto call forwarding and voicemail to e-mail.

  • Cost savings all round.

    Not only do you save money on call costs and line rental, you could also eliminate the cost associated with maintaining and upgrading a traditional phone system.

  • Improved efficiency.

    The portability of your VoIP number means you can take your connection with you, wherever you go. Ideal for employees who travel both locally and abroad. What’s more, its web based functionality means it integrates seamlessly into other functions like e-mail, fax and conference calling.

  • Keep your numbers.

    A common misconception is that switching to VoIP means you have to change your phone number, resulting in unwanted administration. VoIP providers actually offer a number porting facility as well as additional landline and Freephone numbers to support your business as it grows.

  • Security is paramount.

    Much like other providers of sensitive online services such as online banking and digital payments, VoIP developers are constantly building sophisticated defence measures like firewalls, redundancy and encryption to ensure your business data remains secure.

  • Easy to manage.

    Working alongside a dedicated communications provider makes managing your VoIP solution simple. Adding or removing a user, installing additional lines, setting up call forwarding or amending your system configurations can all be achieved promptly using a dedicated web portal.
